T 0 all whom it may concern: Be it known that I, MILTON A. FESLER, a i citizen of the United States, residing ati Visalia, in the'county of Tulare and State l of California, have invented certain new i and useful Improvements in Fluid-Cooling Means for Gasolene or other Engines, ofl which the following is a specification.

The object of the present invention is to provide means for cooling the water circulating in the water jacket of a gasolene or explosive or internal combustion engine, or for condensing the exhaust steam from a steam engine. 7

The invention can be applied equally well for both of the above purposes but for illustration it will here be shown-as applied for cooling the water of circulation in-the water jacket of a gasolene engine.

In the accompanying drawing, l*igure 1 is a side elevation of the engine; Fig. 2 is a section of the fly wheel on the line 2-2 of Fig. 4; Fig. 3 is a vertical section through the relief tank; Fig. 1 is a section on the ho 4-4 of Fig. 1.

Referring to the drawing, 1 represents the shaft of a twocylinder engine, such as is commonly used for automobiles, having cranks 2 driven by pistons in the cylinders 3, all of the usual construction. Upon the projecting end of said shaft is secured the fly wheel 4 in which my invention is mainly embodied. Said fly wheel comprises a hub '5 secured upon the shaft, a hollow rim 6, and hollow spokes 7 extending from said titions 8, said rim is divided into compartments 9, each connecting with two ad acent hollow spokes, so that the number of compartments is one-half the number of spokes. For the purpose of illustration it may be l supposed that there are eight such spokes l and four'such compartments.

The water of circulation passes from the tops, of the water jackets 10 by pipes 11 to inlets 12 in an outer tube 13, which tube discharges at its end into an annular chamber 1 -1- fcrmcd in the hub 5. of the fly wheel. 5 From said chamber it flows by means of four passages 15 formed in said hub into four of the hollow spokes 7 thus entering the four compartments in the hollow rim. From said compartments it flows back by the other four spokes 7 to passages 16 formed in the hub of the fly wheel and thence to a chamber 17 formed in said hub means of stuffing boxes 20, 21. The runner 22 of the pump is secured upon a small shaft 23 extending from, and revolving with the shaft of the engine. By means of said runner the water is forced out of the casing 19 and flows by two pipes 24 to the lowest parts of the water jacket. In these water jackets the Water 15 again heated and circulates 1n the same manner as before, the

change in temperature which here takes place assisting the circulation positively cffeeted by the centrifugal pump.

In order to allow for the expansion and contraction of the water as it varies in temperature there is provided a small receptacle 25 connected with the water circulation and closed by a plug 26. WVhen the water and the contained air-expand owing to the rise of temperature the air can escape through a small vent hole 27 in the plug.

In passing through the hollow spokes the water is exposed to a great extent of cooled surface, the spokes being comparatively wide and thin, and in order to increase the cooling etfect, saicl spokes are arranged, oblique to the airis of the fly wheel somewhat I like the blades of a rotary propeller. This form induces a strong current through the fly wheel which has a rapid cooling effect on the surfaces of the spokes and the rim of the fly wheel, thus tending to rapidly cool the water circulating therethrough. The mode of application of the invention to condense the exhaust from a steam engine is obvious. It is also to bev observed that, .on account of the centrifugal pump, operating in unison with the shaft of the engine, the circulation and therefore the cooling effect increase in proportion to the speed of the engine, a very desirable result.

To cool the water in water jackets of gasolene engines of automobiles, or condense the steam in those which are propelled, it is customary to rely principally or one tirely upon the movement of the vehicle itself to provide the current of air which cools the water or steam, as the case may be. It is iii no that in some cases a fan is used to assist this cooling effect, but this assistance is comparatively slight, and moreover it necessitat' the employment of extra parts.

By the present invention the radiator connections, and of a vention this cannot take place, and consequently there is the fly whee pipes at present in common use with automobiles and which are exposed to the cur rents of air as the vehicle is traveling are in the present invention the water of circulation is added to the weight of the fly wheel, and in fact forms part of the fly wheel, and thus not only is the weight of the pipes avoided but the weight 01: the water itself is utilized to form part ofthe fly wheel, thus saving in the amount of metal required to beused for the fly Wheel. Hence manunow dispense and water pipes and considerable part of with the water tank,

the fly wheel.

A further important advantage of the present invention is that the water, being much more effectively cooled than with prior devices for this purpose, cannot reach the boiling point, and there is much less escape of water by evaporation. With prior devices, in hot climates, or Where the roads are hot and dusty, or where the engine is running while thevehicle itself is standing still and consequently there is not suflicient I circulation, it frequently happens that the water of circulation reaches the boiling point and consequently passes off as vapor and has to be renewed. With the present in not the necessity of furnishmg a large water tank for holding asuflicient supply of water, to provide for-this evaporation.

It will of course be the .present'invention the water can be kept cold while the car is standing-still, just'as well as when it is moving, because the motor can be started to run at any speed whicheflects a rapid circulation.

One of the greatest annoyances in automobiling is the carbonization "of the-lubricating oilwhich wears outthe piston and cylinder and this carbonization' iscaused to great extent by over-heating. By means of the present invention, in efl'ectually accomplished, this over-heating and consequent carbonization are avoided.
